Shaft yopingasa yomwe ili mu differential ndiye gawo lofunika kwambiri la cholumikizira cha shaft choyendetsa, chomwe chimagwiritsidwa ntchito kutumiza mphamvu ndi kuyenda. Zigawo za shaft ndi mtundu wa zigawo zomangira zomwe zimagwiritsidwa ntchito mochuluka ndipo zimakhala ndi malo ofunikira kwambiri. Ntchito yayikulu ya zigawo za shaft ndikuthandizira zigawo zotumizira ndikutumiza kuyenda ndi mphamvu. Zimakumana ndi zovuta zosiyanasiyana panthawi yogwira ntchito. Zipangizozo ziyenera kukhala ndi mphamvu zambiri zamakanika ndipo zimafuna kuuma kwina kuti ziwongolere kukana kwawo kutopa.
Kusankha zipangizo za zida kuyenera kutengera zinthu zapakhomo, kuyesera kusankha zipangizo zomwe zili ndi chuma chambiri m'dziko lathu, kuyesera kusasankha zipangizo zamtengo wapatali zachitsulo, poganizira kuti zidazo zimakhala ndi katundu wosinthasintha nthawi zambiri panthawi yogwira ntchito, kotero ma forging amasankhidwa, kotero kuti ulusi wachitsulo ukhale wotsika momwe zingathere. umadulidwa kuti zitsimikizire kuti zigwiritsidwe ntchito bwino. Zipangizo za cross shaft ndi 20CrMnTi, yomwe ndi chitsulo chopangidwa ndi alloy yochepa ya kaboni. Ndi chinthu chofala chomwe chimakwaniritsa bwino mawonekedwe a makina a cross shaft ndipo ndi chotsika mtengo pamtengo. Kusankha zipangizo ndikoyenera.
Pakati pawo, kusankha malo opanda kanthu ndi kusankha zinthu za cross shaft ya differential gear kuyenera kukhala ndi mphamvu zinazake komanso kukana kuvala malinga ndi zofunikira za ziwalozo. Kawirikawiri, mapangidwe a alloy otsika kaboni (zipangizo zopangidwa ndi carburizing) monga 20CrMnTi nthawi zambiri amagwiritsidwa ntchito. Kuphatikiza apo, poganizira mtundu wa kupanga kwa zinthu zazikulu zambiri, Pambuyo pa carburizing ndi kuzimitsa, pamwamba pake pamakhala kuuma kwakukulu pomwe gawo la axial limasunga mphamvu ndi kulimba kwakukulu, ndipo mawonekedwe ofunikira amakina ndi okwera, kotero njira yopangira die forging yokhala ndi magwiridwe antchito komanso kulondola kwambiri imatsatiridwa.
